The correct answer would be the third option. The correct plan for the experiment would be that the type of salt and the amount of water are controls, and the amount of salt and the density are variables. Sheila wants to know the affect of varying the amount of salt to the density so it is the density and the amount of salt that is being changed while the type of salt and the water are kept constant since they are not being investigated.

Which population is limited by density-dependent factors?
dedylja [7]

Answer: (c) A local wolf population experiences a lethal epidemic of parvovirus.

Explanation:

A limiting factor is one which is capable of limiting the population of the species. It can be a living factor or a non-living factor.  

The density dependent limiting factor is a factor which affects the population of a species depending upon the size of the population. There are many density dependent limiting factors such as disease, migration, predation and food.  

C is the correct option, this is because of the fact that the epidemic outbreak can spread over to the large number of members of the population. If larger the population size more likely will be the chances of spreading.
